From d3c7b77d1a6e7a0a27035a7ba723a3455317883e Mon Sep 17 00:00:00 2001 From: Marcelo Tosatti Date: Mon, 23 Feb 2009 10:57:41 -0300 Subject: KVM: unify part of generic timer handling Hide the internals of vcpu awakening / injection from the in-kernel emulated timers. This makes future changes in this logic easier and decreases the distance to more generic timer handling.
